Facebook app user likes without big red alert - javascript

I'm making the Facebook app whit JavaScript SDK, and I need user likes permissions to make a like gate. When I go to my app for the first time I get the popup whit permissions and big red alert: "The following permissions have not been approved for use and are not being shown to people using your app: user_likes " When I submit my permissions for approvement they reject me... Is there another way to make a like gate?

If you're having a Page Tab App, then use the signed_request data. If not then you'll need the permission to be able to access the User's likes.
Have a look at my answer here: perl Facebook::Graph API check if user likes page

How to get response from FB page like in angular 5

I am using ngx-facebook for implement FB page like. I want to know if my FB page was liked or not to perform some action on basis of response.
I followed "https://www.npmjs.com/package/ngx-facebook" tutorial to implement FB like.
Rewarding users in any way for liking a Page is not allowed. The only way to know if a user liked a Page is to authorize that user with the user_likes permission. After that, you can check if the Page is liked. You will not get that permission approved by Facebook though, if you reward users for liking, or gate content behind likes.
TL;DR: It´s not possible and not allowed for your use case.

Fixed Facebook user ID for your login system

I am building a login system that depends on Facebook login plugin (https://developers.facebook.com/docs/facebook-login/web). Everything is going well with this easy to use plugin. The bad news is that: today, I noted that the Facebook changes its user IDs, and these changes can deceive your login system.
Explaining the process and the problem:
1- The user goes to your website and click Facebook login button to access to your website.
2- The plugin grabs the user's information from Facebook API, including the user Facebook ID.
3- Your script uses the grabbed info to check your database, looking for the Facebook ID in the users table.
4- If the Facebook ID exists, the system allows the user to login. If it does not exist, the system creates a new account for the user and login him/her to your website.
So, the same Facebook user might be registered more than one time as long as the Facebook changes the user's ID.
As I noted today: Sometimes, the Facebook gives its user an ID with 9 digits, and other times give the user an ID with 19 digits. If you used any of those IDs; it would redirect you to the same user's profile. For example: if the user's IDs are 999999999 and 1010101010101010101
https://facebook.com/999999999 and https://facebook.com/1010101010101010101 both URLs will lead you to same profile.
P.S. The script checks with the user's email, however the user has the choice not to supply his/her email address to your website.
I use API v2.. I didn't use the old version (v1.). So, I think this is not the issue of chronicle or app scoped IDs.
If you have any ideas that help in getting a fixed Facebook user ID, please let me know.
Thank you in advance

If I am not wrong to create a Facebook login button you need to create an app to obtain api keys, right?
If it is the case the problem could be the following:
After testing the login button you have to make the app publicly available by passing a review process from Facebook, and then anyone will be able to login to your website with a Facebook account.
As said: this is the process for standard apps, at the moment I am not sure at all about if it is exactly the same process for logins.

LogOut user from Azure mobile Service from hybrid mobile app

I am following authentications steps for AMS as described here:
http://azure.microsoft.com/en-us/documentation/articles/mobile-services-html-how-to-use-client-library/#caching
From Kendo UI mobile app (Javascript)
I can log in using Google as an authentication provider using client.login("google"), execute authenticated AMS custom API calls
and also doing client.Logout() via button, that seems to successfully disconnect me from AMS
On subsequent client.login(), however, I do not get the Google account login window. It is seemingly stored in a cookie and the user is logged in automatically, thus not giving me a chance to log in as another user.
I was wondering what additional actions besides client.Logout() I must do to initiate the Google login screen on the next session after the user decided to logout. I do not want to force the user out of his Google account, as this would be impolite, just log him out of my application.
I know this question is old, but since it is not answered and I found it out recently I decided to post the answer here.
When you go to google.com you can add another account (top right icon). After that you can choose after each logout which account you want to use for your application to login. And you can even add other accounts to log in.

Facebook Graph API - Get profile picture prior to authenticating

Ok so i've tried the following:
FB.api("/me", {fields: "picture"}, function(response){
console.log(response);
});
And i'm trying to work around http://graph.facebook.com/USERNAME_OR_USERID/picture since obviously i don't know the users ID prior to authenticating.
All i want is a "modern" feel within the website, so i'd like to present the user with his or her's profile picture on the "login" div presenting the facebook login button. Is this possible? I know that Facebook and their graph api prohibits most such features but i would hope that a public profile picture would be accessible through the graph API..
I've Googled around and all the solutions say "use the USERNAME in the URL and you're fine" but i'm not, so to clear out any doubts, is this possible?
Error message: An active access token must be used to query information about the current user.
You can get everyone's Facebook profile picture without authentication.
You just call http://graph.facebook.com/USERNAME_OR_USERID/picture?type=large. This URL redirects you to image URL.
Type may be normal,small or large.
I also have questions for you:
How do you want to display the picture of someone without knowing who he/she is?
How can you guess which account the visitor will use to connect?
It looks like you want to know whose Facebook account was lastly connected on the browser of your visitor. Technically, you would want to read another site's cookies, which is 1) not allowed 2) impossible.
Several additional things you need to know:
http://graph.facebook.com/USERNAME_OR_USERID/picture is a public way to retrieve someone's photo. You don't need a token for that. What else do you need?
Using FB.API("/me", ...) from the JS SDK implies that "me" represents the connected user. It cannot just be used alone.
By the way, identical questions have already been answered and accepted:
Facebook app without prompted authentication
Get Facebook user's profile picture prior to authenticating app
Why would you hope the impossible?
